Application filed April 8, 1905. Serial Ho. 254,647-

To all whom it may concern.-

Be it known that I Roemi'r D. Wane, a citizep of the United tates,residing at Mmden, in the parish of Webster and State of Louisiana, haveinvented certain new and useful Improvements in Automatic Wei hing andDumpin Machines, of which the fo low- 111%!8 a spool cation.

ly invention relates to automatic wci hmfi and dumping machines, whichmay e di erently constrdcted, but preferably has many of the features ofmy application'for Letters Patent Scrial No. 245,571; and my inventionconsists in the arrangement of toggles in connection with scale-beams,each swin 'ng from the same axis, and in providin t e receptacles withmovable bottoms or va ves and means for locking and openin the same, asfull set forth hereinafter, an as illustrated in t c accompanyingdrawings, In whichhi re 1 is an elevation in art section of a mergingand dumpin mac 'ne embodyin my improvements. lg. 2 is a sections an. 7Within the mouth of the chute or hopper t, communicating with the sourceof'silpply, is centrally pivoted a valve I), having two faces divergmfrom the center downward, so that when t e valve is in one position thechute will be opened above a receptacle supported by one of two scales BB and when in the other position will be opened above a receptaclesupported by the other scale. These scales may 9 pivoted in any suitablemanner-as, or instance, in my application, SenalNo. 245,671-bntreferably the are suspended from a centre pivot or she I: a, supportedby a main frame 0. Each scale conslsts of a beam 1 and may be providedwith the usual suitable adjustable weights and munterwoi hts, asdesired. Sus nded to the scale cams below the mouth of the chute at eachside are receptacles m and m, which may be suitably connected. Thus eachof the beams l ie connected to operate the valve 3), a hair 0 beingconnected to the {amt of a toggle r r and to the'scale-bea'm I Wit? andone member of the to gle being connected to an arm 9 on the sha t f ofthe valve, as illustrated, so that as either rece tacle sinks-as, forinstance the receptac e m'--the connected toggles will be broken and thevalve D will be swung to one side to close the chute above thedescending rece tacle while the rising of the other reeeptac s willstrai hten the toggle connected therewith and inter-pose its members ina straight lme between their pivot and the arm 9, so as to hold thevalve D in its new position during the filling of the elevatedreceptacle. When the latter is filled, its weight will canse itsdcseent, breaking the toggle to which the receptools is connected, a amshifting the valve, which will be secured in its new osition as theopposite receptacle reaches t a limit of its upward movement. It will beseen that owing to the connections shown as one receptacle descends itsweight will be exerted to lift the other receptacle.

With the above-described parts are combined means whereby the materialin each receptaclo, as soon as the latter has been propor y filled, willbe discharged, and the titscharge from both receptacles is received by achute E, or in an suitable way, from which it may pass to a ag heldbeneath or to any convenient receiver. As shown, each receptacle m m isof metal or other suitable rigid material and is 'rovidcd with a bottom1;, hinged to one si e at w connterweighted, if necessary, and providerwith anarm or extension it, between which and a pint on the receptacleis interposed a to gle s,and a link q extends from the joint 0 thistoggle to a pin p, projecting from the beam Z at a point distantfrorn'th'o point 1 where the receptacle is suspended by, the beam 1, sothat as the beaml swings downward the pin will be carried down with thelink q, moving more rapidly than the receptacle, thus breaking thetoggle a and swinging the bottom 12 to an open position, where y thematerial in the receptacle is discharged. When the receptacle is againcarried upward and the scalebeam takes a horizontal osition, the link qwill carry upward the pivot of the toggles, bringing the two sectionsercoi" into inc, and thereby locking the hinged valve in its closedposition. It will be seen that this is a sitive movement alternatelyclosing and coking the inlet-valve and alternately 0 ening and closingand locking the hinged )ottorns er the receptacles, so that as one fillsthe other discharges.

It will be evident that other forms of movable bottoms or valves vforthe receptacles may be employed, as well as other means for causing thesame to be opened when the scale is tilted or otherwise moved on thereee tacle receiving its charge.

ithout limiting mysel to the precise construction and arrangement ofparts shown, I l of a receptacle supported by each scale-beam claim asmy invention 1. The combination in an automatic weighing-machine, of achute, a valve at the mouth of the chute, two scale-beams having acommon pivot below said valve and supporting receptacles, two toggles,each connected to operate the valve, and a link between each toggle andthe scale-beam supporting the receptacle below said toggle,substantially as set forth.

'2. 'lhecombination in aweighing-machine, of a chute, a valve at. themouth of the chute, two scale-beams pivoted at their inner ends andextendingoutward in oppositedirections, toggles connected with the frameand with the valve, and links connecting the joint of each toggle withthe adjacent scale-beam, substantially as set forth.

3. The combination with a chute and with a valve hin ed in the mouth ofthe chute to open and close opposite sides thereof alternately, of twoscale-beams, each having a long and shortarm, the short arm of each beamsupporting a receptacle, a toggle, aml a link connecting the same witheach short arm, said toggle connected to the frame and to the valve,substantially as set forth.

4. The combination with the valve and scale-beams of an automaticweighing and dumping machine, of a receptacle supported by eachscale-bmim, and provided with a. movable bottom or valve, a toggleconnecting the valve to the receptacle, and connections between the toglc and scale-beam whereby to open said va ve as the receptacle beginsto descend when filled,snbstantiallyas set forth.

5. The combination with the chute, valve and scale-beams and receptaclesof a wei hingmachine, of connections between the cams and valve forshifting the latter to open and close the mouth of the chute at oppositesides alternately, a bottom hinged to each receptacle and provided withan arm and with a toggle extending between said arm and a point on thereceptacle, and connections between the to glcs and the beams wherebythe sections 0 each toggle are brought into line as the receptacle risesand are carried out of line as the receptacle descends, substantially asset forth.

6. The combination of the chute, valve, scale-beams, toggles r rconnected bv links to the beams, receptacles irovided with pivotedbottoms, toggles 8 am connections between the toggles a and thescale-beams, substantially as set forth.

7. In an automatic weighing and dumping machine, the combination withscale-beams,

and provided wit 1 a movable bottom or valve, and toggles connecting thereceptacle and valve, and connections between the toggles andscale-beams whereby the valve is opened on the descent aml closed on theascent of each receptacle, substantially as set forth.

S. In an automatic weighing and dumping machine the combination of thescale-beams, receptacles, a bottom hinged to each receptacle andprovided with an arm and with a toggle extending between said arm and apoint on the receptacle, and connections between the toggles and beamswhereby the sections of each toggle are brought into line as thecorresponding receptacle rises and are carried out of line as thecorresponding receptacle desccnds, substantially as set forth.

9. In an automatic weighing and dumping machine, the combination withthe main inlet-valve and scale-beams, of a receptacle, supported by eachscale-bemn, provided with a movable bottom or valve, toggles connectingthe valve to the. receptacle, and connections between the scale-beamsandthe toggles whereby the bottom of each rece taclc is opened when theinlet-valve is closet and vice versa alternately, substantially as setforth.

10. In an automatic weighing and dumping machine, the combination of thescaleboams, receptacles supported by said scalebeams and provided withmovable bottoms or valves having toggle connection with the receptacles,and connections between the toggles and the beams whereby the members ofeach toggle are brought into line as the corresponding rccc tacle rises,thereby closing the valve and locliing it in closed position,substantially as set forth.

11. In an automatic weighing and dumping machine, the combination of thescalebeams, receptacles supported by said scalebeams and provided withmovable bottoms or valves having toggle connections with thereceptacles, and connections between the toggles and the beams wherebythe members of each toggle are carried out of line as the correspondingreceptacle descends thereby opening the. valve and holding it in openedposition, substantially as set forth.
